Uur invention relates to lubricating devices, and is exemplified as appliedto a socalled metal shaping machine, although our invention is applicable to other metal workingn1acl1ines,'iu which the combinations set iorth in `the claims inaybe employed.

ln thisI exeiuplilieation there is a ram arra: ngcd to be operated by a rockerarni ypivoted at a lower portion and having articulating connection with the ram at au upper portion, a crank being arranged to reciprocate the rocker-erin.

lt is the object ot our invention, to provide a plurality of lubricant 'feeding reservoirs, and a plurality of lubricant collecting reservoirs, a portion of which serves for both collecting and feeding the lubricant, arranged in novel manner so -voirs lubricate the bearings at different parts of theinachine, and so that lubricant overflows Atroni one reservoir to the other and is rcturned to the primary reservoir 'for reuse; and, further, to provide a lubricant Jfeeding reservoir with novel filtering means so that be cleaned by filtration.

/ lt is the vobject of ourinvention, further to provide novel lubricating means for the ram operating mechanism, comprising a lubricant passage through which the lubricant moves upwardly for reaching an upper point of lubrication; tiutl1er,to so arrange such passage that it moves' with the rocker-arm for main'- tainingproper correlation between the outlet Y of the lubrcant' passage yand said upper point of lubrication and, further, tov provide. novel lubricating passages at the supporting portion ot the rockerarm for passage of the `lubricant therethrough. f f

llt is the object ot our invention, further, to

l provii'le'` such ya rocken-arm with ine-ans, including novely lubricant passages, so

that the lubricant passes through said bear ing means during rocking movements of the Tockenarln and, further, to provide novel lubricant passages for' the linka'nd articula-v tions between the link and said rocker-arm and rain respectively.

4 The rocker-arm is rocked by means ofi a crank'41, on the bull-wheel 42, having a^hub 43 journaled in a bearing 44 on the frame.

The crank is on a crank-slide 45, adjustable in usual manner in radial direction on the bull- Wheel toward and from the axis of the bullwheel for adjusting the lengths of'stroke or angles of reci `)rocations of the rocker-arm. The crank is journaled in a crank-block 46 which has reeiprocation in a guideway 47 in the rocker-arm, the crank-block having slide connections with the walls of said guideway. f Y

The bull-wheel comprises a gear 51. Apinion 52 meshes with the gear and is on a shaft- 53 journaled in bearings 54, 55, in the frame. This sha-ft' and the' bull-wheel are driven members. The shaft 53 has various Speeds imparted thereto by drivin gearing which comprises suitable speed c ianging mechanism communicating with gearing on the shaft 53 for imparting various selective speeds to the shaft 53 and thereby reciprocating the rocker-arm at different speeds. This speed changing mechanism may comprise suitable gearing on shafts 56, 57, 58, journaled in bearings in a housing 59, show-n as a bulge in the frame. f

The shaft 56 is exemplified as journaled in bearings 61, 62, 63, in the housing. The shaft 57 is shown journaled inl said bearing 64, 65, and the shaft 58 is shown journaled in bearings 66, 67, 68, in said housing. Some of these bearings are shown as ball bearings, others as roller bearings, but in torni they may be any suitable bearings for permitting the The shaft `58 is shown as having a pulley (39 thereonfor receiving rotation from a suitable electric motor or other device.

The speed changing gearingmay be of any suitable form and arrangement and provided with any suitable control means, and may comprise gears indicated generally at received about said respective shafts 56, 57, 58.

The eitem lited means, for lubricating the various bearlngs and journals therein and the ving parts will now be dc- 'ho/les are shown openinginto grooves 77 in the bottom ofthe reservoir, forming ribs bctween said grooves.

A filtering pad 78 is received in said reservoir upon said bottom for causing the lubricant, for instance oil, to tirst pass through said filtering ad and thereby purify the oil before it is de ivered to said holes. The elcvations, exemplified by the ribs, raise the tiltering pad above the bottoms of the depressions, exemplified as the grooves, for forming lubricant spaces between said pads and the lubricant passages. f1

A cover 81 is received over said reservoir and may, if desired, have a tight joint therewith for sealing said'reservoir in order that pressuremay be maintained on the oil therein, if desired, although our invention contemplates that the lubricant may be fed to the 'Various points ot' application by( gravity. When it is desired toy clamp the cover upon the reservoir, bolts 82'tlireaded to the wall of the reservoir and passing through the cover may be employed. Th/e sides of the reservoir may be provided with sights 83, which may be of glass, suitably fastened in the sides of the reservoir, for observation of the height of the oil in the reservoir. y

The wall 27 is'provided with a recess 85 with which a lateral passage 8G in the ram communicates. The wall 29 is provided with a groove 87, which extends lengthwise of the vram and with which said lateral passage, communicates. An absorbent pad 88 is received in said recess, and is arranged to wipevupon the wall 26 for lubricating complcmental Yalls 26, 27.

A lateral passage 89 communicates with said groove at various points along said groove. dil-ring the reciprocating movements of the ram.

The wall 28 is provided with recesses 94,1, 92, in which absorbent pads 93, 94, are rcceived. A lateral passage 95 communicates with each. of said last-named recesses. There are similar structures at the other side of the ram designated by similar but primed reference numerals. A pipe 96 extends from the primary reservoir to each of the lateral passages, there being threevof these pipes for the three lateral passages exemplified at one side of the ram. Similar pipes 96 extend from the primary reservoir and'communicate with the lateral passages at the other side of the between the ram-and the frame and leads to the bearing 44 A bearing bushing rain, there being also three of these pipes exemplified. Thesepipes are connected in suitable manner with the holes in the bottom of the primary reservoir.

The latter pipes cross the path of the recip? rocating rocker-arm in the form of loops 97.

The reservoir is located above the guides so that the lubricant in the reservoir may, if desired, reach the point of lubrication by gravity. 4

Pipes 101, 102, extend from holes in the bottom of said reservoir throughthe opening 74, and are receivedat their other ends in holes 103, 104, the shaft 53 for lubricating said bearings. The bearings may be provided with narrow longitudinal slits- 105, 106, for respectively vreceiving the oil and distributing the same lengthwise ot the journal and fpermitting drainage of oil from the bearings into the interior of the machine. All the'bearings are preferably provided with such slits, some of the slits being'shown. 1 A pipe A109 is connected' vtith one of the holes in the bottom of the primary reservoir for the hub 43 of the bull-wheel.

The 'link is pi'ovidedwith a foik'152 at one end, the tinesot' which have bearings 153, between which a cent-ral bearing 154 at the upper'cd fork 157 on the` therefrom and opening at the journal faces of the bearings 156.

The passage 162 in the journal pin 33 has a laterally extending'branch 167, which communicates with a groove 168"below said pin in the upper bearing 154 of the rocker-arm. This groove continues asa groove 169 on the loop 170 of the rocker-arm, forreceiving oil from the oil recess 151 in the link into 'a lubricant recess 171 at the side of said loop on said rocker-arm. A. lubricant passage 172 extends from said recess, through which the oil passes and drips into an oil-recess 174 1n the4 upper end of the crank-block 46. lThel lower end of thisvoil-recesshas a hole 175, which communicates with the .journal face in the bearing in the crank-block. Filter pads 176 are located in slots inthe side edges of the crank-block, holes 17'7 communicating therewith from the oil-recess 174. These filter pads contact with the slideway in which the crank-block reciprocates for lubricating thevsan'ie.

An inflow pipe 181 communicates `with a pump 182, and is connected with a passage 183 in the primary reservoir., An out-dow pipe 184 is connected with an out-ow passage 185 in said reserroir, and with a hole 186 in a-secondary lubricant reservoir 187, shown located above the driving gearing.- The inlet opening and the out-flow opening in the primary reservoir are preferably so related as to maintain a body vof lubricant in the primary reservoir for feeding the sa-me to the various points of lubricant supplied thereby. yThe height of this body of lubricantmav be observed through the sights 83.

It is instanced that there is a gravity feed lof the lubricant through the pipes supplied by the primary reservoir, and the passages which supply the rocker-arm and its connected parts with lubricant, is shown of greater diameter than the passages supplying the respective bearings, for the reason that there is an up-ow of the lubricant from the bearing means at the lower end of the rockerarm to the points of lubrication at the upper end of the rocker-arm, the lubricant flowing upwardly to these latter bearings, due to the weight of the lubricant -in the primary reservoir and the down-flow passage, and the fact that the primary reservoir is located above the level of the guideways for the ram, and

the oil seekingits level throughout the pas-1 sages. The out-dow passage 184, 185, is also preferably of greater diameter than the individual feed ipes, as the lubricant for the secondary fee ing reservoir, the bearings for the drive shafts, and the lubricant collecting reservoir therebelow are supplied throughV this passage.

The secondary lubricant feeding reservoir 187 is provided with a suitable number of holes 188 in itsbottom, communicating respectively with cross-grooves 189, forming ribs 190, on which a filtering pad 191 rests, forming lubricant collecting spaces under said pad. The holes 188 have sets of pipes connected therewith, which feed the lubricant tg the bearingsiof the respective shafts 56, 5 58.

Thus pipes 192, 192", 192, communicate withcertain of the holes-188, the other ends of said pipes having communication with holes 193, 193", 193, in the bearings 61, 62,

` 63, in which the driving shaft 56 is j ournaled.

Pipes 194, 194", communicate with certain of the holes 188, the other ends of the pipes being received in holes 195, 195", in the bearings 64, 65, of the driving shaft 57. Pipes 196, 196", 196, communicate with others of the holes 188. The other ends of said 4pipes Ycommunicate with the bearings 66, 67, 6 8, of

the shaft 58. v An out-flow pipe 201 is received in' thesecondary lubricant feeding reservior for receiving oil therefrom and dripping the same into the lubricant collecting reservoir 202 located below 'said driving gearing. The upper end of this lubricant passage is preferably at such height in the secondary lubricant feeding reservoir as to insure that a body of oil or lubricant is in the secondary lubricant feeding reservoir. This lreservoir is provided with a cover 204 which is removable. The supply of lubricant desired for lubricating the mechanism is preferably poured into said reservoir. A

Lubricant pipes 205, 206, communicate with holes in the bottom of the secondary reservoir, the pipe 205 communicating with a hole 207 in a bearing 208. This bearing has a shaft 209 therein, which is driven from the drive shaft 58, as by means of'spiral gears 210, 211. This shaft has a crank plate 212 fixed thereto, with the crank 213 of which a pitman .214 is articulated, the 'pitman having articulation 215 with a piston rod 216 of the pump 182. The pipe 206 opens above the crank plate for feeding lubricant tosaid articulations. j

The pump, as instanced, comprises a piston 221 on said piston rod 216, which reciprocatesV in a cylinder 222, a suitable packing 223 being received about said piston rod. The pump has an iii-feeding port 225 and an out-feeding port 226, with which the inflow pipe 181 connects. A sieve 227 is received about said inlet port.` Valves 228, 229, are arranged to los be respectively seated upon valve seats 230.

231, in alternate order, upon/reciprocation of the piston, for causingliow of oil through the pump to the primary reservoir.

An out-flow passage 235 communicates with the primary collecting reservoir, surrounding said vpassage for determining the level oflubricant in said collectin reservoir and suppl ing a body 237 of lu ricant therein, into w ich drive gears which are on the shaft 58 are arranged to dip for-feeding supported by a brachet'2ll0 extending from the frame.

fn' order to control the flow of lubricant from the primary lubricant feeding reservoir 7l to the various pointsof lubrication served thereby and to the secondary lubricant feeding reservoir, li prefer to provide regulating means in the passage between said lubricantl feeding reservoirs, instancedas a valve 243 having a handle 244, which isaccessible from the outside of the machine for regulating the lubricant passing to the secondary feeding reservoir, 1n order to insure that all ofthe lubricating points supplied by the primary lubricant feeding reservoir ave suiiicient lubricant. rllhis lubricant controlling means is especiall useful when a force feed is provided for tile primary lubricant feeding reservoir. v

ln our improved device the lubricant is pumped from the lower collecting reservoir to the primary feediner reservoir. The lubricant passes thence to t evbearing means at the lower end of the rocker-arm, and thence upelli wai-diy to the articulating means at the upper end of the rocker-arm. Lubricant also passes through the passages supplied from the primary feeding reservoir to the ramslide and to bearings of the shafts of the driven gearing.

All of the lubricant thus fed 'is first filtered in said primary reservoir. The primary lul bricant fe'ding reservoir 1s preferably lotiti cated at a high point so that the Afeeding of the lubricant may be by gravity if desired. lt is elective however that the lubricant from the primary reservoir maybe fed under pressure supplied by hclosing said primary reservoir and feeding the oil thereinto under pressure.

'lhe sur lus lubricant passes from the-primary lubricant reservoir through the passage 184C into the secondary lubricant feeding reservoir. From the secondary lubricant feeding reservoir the lubricant passes to the rective bearings 4for the driving gearing a wall 236 lower lubricant reservoir,

lfeeding reservoir.

`under the latter, and

preferably including speed changin in@ and to the pump mechanism. his llibricantv is also referably first filtered before entering the lu ricant passages. A body of lubricant is'insured in this secondary lubricant reservoir by the height of the opening of the out-flow or over-flow passage therein,

through which the surplus lubricant passes to the lubricant collecting reseivoir under the driving gearing, a portion of which driving gearing is arranged to dip into said collectingv reservoir for further lubricating the gearing.

rlhe lubricant is fed from the secondary lubricant feeding reservoir preferably by gravity, but if desired, it may be fed under presi sure by maintaining a pressure in said sec-` ondary feeding reservoir, the pressure being obtained by lirmly clamping the cover u on said reservoir an cant under pressure thereinto from the pri` mary reservoir. y. e

the primary collectrf he surplus oil from ing reservoir is arranged to overflow into the from which the oil is again pumped to the primary lubricantl 'fhe lubricant may in the bearings and bricant collecting reservoirs.

rlhe lubricant at its various stages of supply is arranged to pass through filtering 4inediums so that pure lubricant is fed to the respective bearings and parts to be lubricated.
